BELT-SHIPPER.

SPECIFICATION forming part of Letters Patent N 0. 724,123, dated March31, 1903.

Application filed June 30,1902.

To all whom it may concern:

Be it known that I, OSCAR L. OWEN, a citizen of the United States,residing at W'hitinsville, in the county of Worcester and State ofMassachusetts, have invented a new and useful Improvement inBelt-Shippers, of which the following is a specification.

In the transmission of power to machines by means of a belt a loose anda tight pulley are used. When the machine is in operation, the belt ison the tight pulley, which transmits the power to the machine. When themachine is stopped, the belt is supported on the loose pulley, which isrotated by the belt, but does not transmit the power. In practice thelever operating the shipper requires to be secured to prevent the beltfrom running from one pulley onto the other, and

thereby stop or start the-machine-when such change is not desired.

In the usual construction of spinning,twisting, and similar machines thedriving-shaft projects beyond the end frame and supports the tight andthe loose pulleys. To more conveniently control the belt and lock thesame in each position, I have devised and produced a belt-shippermechanism by which the belt is automatically locked against lateralcreeping when on the loose as well as when on the tight pulley.

Figure 1 is a top View of the end frame of a spinning-machine, showingmy improved belt-shipper. Fig. 2 is an end view of the same. Fig. 3 is aside view of the shipper mechanism, on an enlarged-scale, showing oneposition, and Fig. 4 showing the shipper mechanism in the oppositeposition.

In the drawings, A indicates the end frame; 13 B, the pulleys; B, thedriving-shaft; B the outside journal-bearing for the drivingshaft, and Bthe'belt. To the end frame A, I secure the bracket 0, which is providedwith the journal-bearings c c, in which the actuaating-rod c isjournaled. The actuating-rod c is provided with" the hand -levers 0 0From the lower part of the bracket 0 the way 0 extends horizontallyacross the two pulleys.

Serial No. 113,840. (No model) The slide (:1 is supported on the way 0and has the shipper-bars d d secured to it. These shipper-bars arepreferably curved and extend beyond each edge of the belt B The slide dis connected,'by means of the curved arm d with the lever d which issecured on the actuating-rod c and swings through the opening 0 in thebracket 0. The toe d on the lever d bears against the bracket 0 and actsas a stop to arrest the outward move-- moving the slide (1 and theshipper-arms from.

one position to the other. In either position the slide is lockedagainst accidental movement and holds the belt against creeping. Asshown in Figs. 3 and 4, the pivots connecting the curved arm d with theslide 61 and the lever d are on the same horizontal plane, the curvedarm extending over and beyond the rod 0 when the parts are in theposition shown in Fig. 3.

Having thus described my invention, 1 claim as new and desire to secureby Letter Patent 1. In a belt-shipper,-the combination with a way, aslide supported on the way, a rotatably-supported rod, and hand-lever onthe rod, of another lever secured to the rod, and a curved arm pivotallysecured to the latter lever on the rod and to the slide, as described.

2. In a machine of the nature described, the combination with the endframe and the pulleys, of a bracket secured to the end frame, a wayextending from the bracket over the pulleys, a sliding support for theshipper-bars on the way, the shipper-bars, a rod supported in bearin gson the bracket, hand-levers on the rod, another lever secured to the rodand a curved arm pivotally connected with the slide and the latter leveron the rod, as described.
